Preventing Future Mesh Modification

Lock a part to prevent modification to the simulation mesh (and prevent the part from being edited).

Some parts of a model take long to mesh or for some reason, it may be required to ensure that a part is not remeshed (remeshing could result in a different mesh). Locking a part allows the mesh to be locked for modification. If the part does not have a simulation mesh, it is meshed once, but the mesh will not be remeshed again (until it is unlocked).

Note: Locking a part to prevent mesh modification is not supported for a voxel mesh.

Select the CAD or mesh part in the model tree (Construct tab).
Lock the part. From the right-click context menu click Lock/Unlock.
The mesh is now locked and will not be remeshed when performing the meshing action.
